Abstract

This invention is concerned about a turbine blade which has an attaching base, a platform outside of the attaching base, and a wing extended out of the platform. The wing has the pressure and suction zone extending between the front edge and the rear edge of the wing. An internal cooling passage network contains at least one inlet on the attaching base and a plurality of outlets along the wing edge surface. This passage network contains a front extending hole of the first feeding passageway. A downward flow hole is on the inside edge of the wing. The front extending hole feeds the downward flow hole which is less cooling fluid. A second feeding passageway makes a present to the first feeding front extending hole.
